2 Claims. 1

This invention relates to filing devices of th type designed for renewing matrices used in typesetting machines and its principal objectresides in the provision of a mechanism which is automatic in operation and afiords a saving in both time and labor in removing the burs which frequently occur on the projecting ears of type matrices and which impair their use in the typesetting machines in which they are used.

Another object of the invention resides in the provision'of a device which embodies the principle of filing only the outer edges of the projecting ears of the matrices to remove the burs therefrom without filing the surfaces nearest the body portions thereof and thus prevent unnecessary wearing of these surfaces.

Yet another object of the invention is that of providing a machine in which an automatic releasing mechanism is arranged to release each matrix individually from a chute in which a number of matrices can be placed so that an entirely automatic operation will result, the matrices being fed in an orderly manner, into an accessible compartment where they can be picked up at will.

Broadly, the invention seeks to comprehend the provision of a device by which type matrices can be periodically filed to remove the burs therefrom without resorting to the conventional hand method, which is both expensive and time consuming, and by which a more uniform result can be realized.

While the foregoing objects are paramount, other and lesser objects will become manifest as the description proceeds, taken in connection with the appended drawings, wherein:

Figure 1 illustrates the invention in perspective, showing the front of the cabinet open and depicting the conveyor belt and filing assembly.

Figure 2 is a fragmentary perspective illustration showing the discharge end of the filing assembly and illustrates a matrix about to be discharged therefrom.

Figure 3 is a fragmentary transverse section of the filing assembly illustrating the manner of engagement of the filing surfaces with the matrices and the relationship of the conveyor belt thereto.

Figure 4 is a detailed illustration of the releasing mechanism showing, in dotted lines, the operation thereof.

Figure 5 illustrates the invention enclosed within an attractive cabinet.

Figure 6 is a cross-sectional view taken on lines 6-6 of Figure 1 showing the filing assembly, the conveyor belt and the motor, a gear reduction box being shown arranged in the device.

Figure 7 illustrates the rails upon which the matrix is originally discharged to be picked up by the conveyor belt and moved upon the stationary files shown fragmentarily, and

Figure 8 is a perspective illustration of a conventional matrix having burs on its projecting ears which should beremoved.

Type matrices through constant use in typesetting machines, such as Linotype, Intertype, and the like, acquire rough protu'berances, and the like, usually occurring on the projecting portions thereof, called ears, which must be removed periodically to insure the smooth and efii'cient operation of the machines. These offending protuberances are commonly referred to as burs and the conventional method of removing them is by laboriously and tediously filing the matrices by hand requiring considerable time and labor.

In addition to the effort thus expended, it is necessary to examine each matrix individually for such burs whether it requires the filing operation or not.

An object of the invention, therefore, is that of affording an automatic device for inspecting each matrix for the burs, as well as to remove the same, thus insuring the efficient function thereof at all times. The entire set of matrices used in the typesetting machine may, from time to time, be placed in the invention and processed therethrough to remove all burs from the matrices and without injury to any which do not require such processing.

The invention, therefore, primarily comprises a cabinet I whose face is preferably inclined, as shown particularly in Figures 1, 5 and 6. A matrix chute 2 is formed in the face to receive a number of matrices 3 stacked therein so that each may be individually released at the bottom of the stack by a'releasing mechanism, shown in Figure 4, which will be presently described. It is desirable to incline the face of the cabinet I in order to incline the chute 2 for obvious reasons, that is, so that the matrices 3 can be loosely retained therein without providing some means for such retention. By this arrangement the matrices can be placed in the chute with a minimum of effort.

In the lower front of the cabinet I is arranged a conveyor belt 4 driven by a pulley 5 and operating over a pulley 6 which is smaller in diameter than the pulley 5. The driven pulley 5 is mounted on a shaft 1 from a gear reduction box B'shown connected to the motor 9 through the shaft l0 thereof in Figure 6.

The pulley 5 is positioned substantially directly beneath the chute 2 and the releasing mechanism therein and is paralleled on each side by bars I I and I 2, shown in Figure '7, upon which the matrices 3 are dropped by the releasing mechanism (Figure 4) and the belt 4 operates between these bars. The stationary parallel files l3 and 14 are joined directly to the bars II and I2 and the rearmost file [3 forms a continuation of the rearmost bar ll, both of these being secured to the front wall I5 of the cabinet I. The bar l2 and the file l4 are'attached to the hinged door files l3 and M, the upper surfaces; of the ears a are yieldably engaged by the serrated undersur faces of the depending integral parallel members l9 of the upper file 20. The latter is arranged longitudinally of the files l3 and I4 and is designed to normally engage the same by reason of the adjustable tension 'assembly 21 thereabove. A knurled screw 22, threaded into the top of the housing ll,- is provided for increasing or lessening the tension of the filing member upon the matrix.

Referring to Figure 4 it will be observed that 2. lug,- or shelf, 23, is provided which is secured to the front wall 4 5 01 the :cabinet -I in the back of the housing 11. l he longer ears 24 of the lowermost matrix 3 rests upon this and a companion lug 25,011 the'door 'l6'of the cabinet, as shown in Figure 1, while the opposite end of the matrix 3 rests upon the outer of a sliding bar '26 of the release mechanism. The bar 26 is slidably supported by a plate 21 secured to the underside of the top of the housing [1, shown in Figure 1, and a lever 28 is providedto .move the bar 26 longitudinally, as shown indotted lines in Figure 4, to release the matrix 3-and drop the end thereof upon the plate 214 The matrix 3 is shown in dotted lines in Figure 4 in an inclined position, the end which has been dropped upon the plate 21 being slightly lower than its opposite end.

The upper end oi the lever28 extends through the bar 26 and through a slot 29 in the plate 2"! while the lower end connected to a rod 30 through the aperture Qltthe lever being pivoted intermediateits ends at d, so that when the lug [8 on the belt I strikes the spur gear 32 on the lower end-of another lever 33 (Figure l) similar to the lever 2'8, and connected thereto by the rod- 30, the bar it is operated in the manner described and the matrix released in the manner described above. A spring '54 arranged upon the rod 35) retains the bar 2G normally in the ,position shown in solid lines in Figure 4, "and when the matrix '3 is dropped to the plate 21, causes the bar .26 to return to .its normal position to engage the end of the matrix 3 and move it forward far enough to release the ears 24 from the lugs 23 and f5 and drop the matrix 3 upon the bars l1 and I2 where itrests until the lug 18 on the .belt 4 engages the same to move it along the filing surfaces b and c.

.As the matrix 3 is dischargedinto a shield 35 formed to cause the matrix '3, when the latter engages the same, to fall with its rearmost end downwardly into a receptacle, or compartment 36 and uniformly stacked,- in upright position as shown in Figure .1 by a star wheel '31. A ten sioned block 33 supports the matrices 3 in their upright position and is capable of being moved along as the matrices 3 are fed into the space 36 provided therefor. The receptacle 36 is readily accessible, being open at all times, so that all or any portion of the matrices can be removed as desired.

Figure 3 illustrates a matrix 3 showing the form thereof which defines the ears 24, and the opposite cars 38, as projecting irom only one 4 of its fiat surfaces, that is, these members are offset with respect to the longitudinal plane along the edges. This arrangement provides for one surface of the matrix 3,- therefore, to be straight along each of its edges to engage the inner vertical surfaces of the files l3 and I4 while the ears 24- and 39 rest upon the serrated surfaces of these .members as in Figure 3. Thus, the burs e, shown in Figure 8, can be removed by the serrated surraces 1) of the files l3 and I4 Without having the edges of the main body of the matrix coming in contact with the filing surfaces b or c of either theupp'er' or lower filing assemblies.

Moreover the files l3 and I4 have their serrated surfaces b formed so that the serrations are arranged along the outside edge of the members l3 and M leaving a smooth edge along the inner sides of these members to insure only the contact of that portion of each of the ears of the matrix 3, which is usually damaged by the burs e, with the serrations b and prevent excessive wear upon the matrix while being processed.- It will be observed that such an arrangement will permit the matrix to be processed an indefinite number of times without injury thereto whether or not any burs appear thereon.

It is apparent that certain changes and modifications may be resorted to from time to time by persons skilled in the art, and such changes and modifications so made as may be considered as falling within the spirit of the invention may also be considered as falling within the scope of the appended claims.
